我有N3383A似乎有损坏RF开关,重定向每个端口之间的电源。
症状是:我可以在R接收器上看到正确的电源(并且所有源衰减器都很好),但是对于任何反射测量和通过所有3端口的测量,功率都非常低。 我知道这个模型已经停止服务,我想知道如何修复它。 我还有另外两台N3383A单元有损坏的电源,所以我想知道将电源模块从第一个单元换到另一个单元是否更简单,或者从带有损坏电源的单元中取出开关并放入第一个单元。 知道怎么做吗? 以上来自于谷歌翻译 以下为原文 I have N3383A that appear to have damage RF switch that redirect the power between each port. The symptom are: I can see correct power on R receiver (and the source attenuator all woks good), however the power is very low for any reflected measurement and thru measurement at all 3 port. I know that this model is out of service and wonder how I could repair that. I have another two units N3383A that have damage power supply, so I wonder if it will be simpler to swap power supply module from the first unit to the other or take the switch from the unit with damage power supply and put in the first unit. Any idea how to do that? |

关于电源,您可以使用任何E836xC PNA的电源进行更换;
即使我们的文档没有说明,它们也是兼容的。 较新的只是具有更多的电流能力。 零件号= 0950-4599。 我稍后会研究你的另一个问题。 编辑:可能是交换机坏了。 这是零件号5087-7137。 该单元中有两个,A22和A23; 有点串联。 您可能想要交换它们以查看是否重新获得部分操作....至少可以验证只有一个开关被烧断。 请参阅框图:http://cp.literature.agilent.com/litweb/pdf/N3381-90001.pdf 以上来自于谷歌翻译 以下为原文 With regard to the power supply, you can replace them with a power supply from any E836xC PNA; they are compatible even if our documentation does not state that. The newer ones just have a bit more current capability. Part number = 0950-4599. I will look into your other question later. Edit: It may be the switch that is broken. That is part number 5087-7137. There are two of them in that unit, A22 and A23; sort of in series. You might want to swap them to see if you regain partial operation....at least that will verify that only one switch is blown. Refer to the block diagram: http://cp.literature.agilent.com/litweb/pdf/N3381-90001.pdf |
